Lisbon Airport roof Impermax 2K

Engineer notes. Not a blog. Lisbon Airport building roof, Portugal. Lisbon Airport Impermax 2K (two-component polyurethane) is the named membrane.
Lisbon Airport Impermax 2K (two-component polyurethane) is the membrane named on the airport building roof in Portugal. Therefore the specifier writes Impermax 2K (two-component hot-spray polyurethane) and the roof use in the same sentence. Ducts and penetrations stay in the details, not in a borrowed floor photograph.
What Lisbon Airport Impermax 2K may carry
Catalogue 2024 prints ETA 10/0296, 25 years (W3), on Impermax 2K, plus root-penetration and asbestos-encapsulation certificates. An aliphatic top coat is required outdoors. Do not move that ETA onto Impermax (one-component moisture-cured polyurethane, 1K PU).
However, do not invent kg/m². Read the current TDS, then the calculator.
See Lisbon Airport Impermax 2K on airport roofs, Impermax 2K and documents.
Outbound reference: EOTA — European Technical Assessments.
First, name the airport roof. Then name Lisbon Airport Impermax 2K. After that, name the aliphatic finish.
These notes do not replace the current TDS, SDS or a written specification. For pack sizes, mix ratio and kg/m², read the current sheet, then the calculator.
